Abstract: ABSTRACT : Character memory addressing for data display.     A means of addressing a character memory of a data display system in which displayed data is composed of discrete characters the shapes of which are determined by selected dots of a dot matrix. When character information conforms to different character modes of the form m x n x b, where m x n is a bit matrix format which is repeated b times to provide b-bits per displayed character dot, the stored character information includes mode bits which identify the mode. These mode bits are obtained by logic control and addressing means by a first address and are used to determine a second address which varies according to the size of the mode and how many bit patterns it contains. The two addresses select all the dot information required for display of characters in real time. Figure 1 shows a typical data display system in which the invention can be embodied.

Abstract: ABSTRACT (Figures 2,4) A planar array (13) of radar antenna elements (B) used in a monopulse detection systems includes means to apply an appropriate phase ? by the phase delay (4) on transmission and reception so as to define only two beams. Received signals are added to give a sum beam (22), and for a normal beam perpendicular to the plane of the array appropriately weighted, signals are added in phase in a resistor network F1.  A single difference beam (27) is generated by added receiver outputs in a second resistor network F2 with each output phase delayed (23) by a phase angle equal to the angular position of the detector measured from the array centre with respect to the array centre line (14).  Then a target position can be defined by taking the ratio of the amplitudes and the relative phases of signals received by the sum and difference beams.  Beam steering is done by applying additional phase delays to both beams to tilt the phase planes of the array as desired.

Abstract: ABSTRACT     Novel solid compositions are provided for assaying the levels of lower alcohols in body fluids.  A carrier is impreg-nated with two or more enzymes, the first of which reduces a reducible agent in the presence of the alcohol.  A chromogen is provided which reacts with either the reducer or the oxidized compound in the presence of a second enzyme or reagent, depend-ing on the system, to produce a clinically significant indica-tion of the alcohol present.  A quantitative determination may be made by the provision of a competitive inhibitor to the first enzyme to provide a graduated response in colour accord-ing to the concentration of alcohol.  Acetaldehyde trapping agents, buffers and enzyme stabilizers are provided as re-quired.

Abstract: ABSTRACT OF THE DISCLOSURE The real time actual  and reference values of parameters  pertinent  to  the  key  safety concerns  of  a pressurized water reactor nuclear power plant are used to generate an integrated graphic display representative of the plant safety status.  This display is in the form of a polygon with the distances of the vertices from a common origin determined by the  actual  value  of  the  selected parameters normalized  such that the polygon is regular whenever the actual value of each parameter equals its reference value  despite  changes in the reference value with operating conditions,  and is  an irregular polygon which visually indicates deviations from normal otherwise. The values of parameters represented in analog form are dynamically scaled between the reference value and high and low limits which are displayed as tic marks at fixed distances along spokes radiating from the common origin and  passing  through  the  vertices.   Multiple,  related binary signals are displayed on a single spoke by drawing the associated vertice at the reference value when none of the represented conditions exist and at the high limit when any such condition is detected.  A regular polygon fixed at the reference values aids the operator in detect-ing small deviations from normal and in gauging the magni-tude of the deviation.  One set of parameters is selected for generating the display when the plant is at power and a second set reflecting wide range readings is used the remainder of the time such as following a reactor trip.

Abstract: ABSTRACT OF THE DISCLOSURE A method of packaging articles of a compressible material, such as cleaning sponges, according to which a blank of arbitrary length is cut such that its thickness corresponds to the thickness of the article and its width corresponds to the longest dimension of the article. The blank is folded lengthwise along its centre line once and is then again folded along the centre line of the once folded blank a second time. The blank, thus folded twice, is advanced through a piece of piping the outer jacket face of which serves as a shaping template for shaping a web of foil into a tubular cover enclosing the blank and the piece of piping coaxially. The tubular cover is brought along by the advancing twice-folded blank at the discharge end of the piece of piping and the twice-folded blank is out while enclosed in the tubular cover, into pieces in such a manner that the length of the blank corresponds to the width of the article.

Abstract: ABSTRACT OF THE DISCLOSURE New logic circuitry for a directional comparison blocking protective relay scheme.  A forward-reaching and a reverse-reaching protective relay located at the local and remote terminals of a protected line segment determine whether a fault is internal or external to the protected line segment.  To carry out this function, the protective relays produce signals representative of fault location and communicate with each other via a communications channel. A fault detector and logic circuitry is provided at each terminal for processing the produced signals to determine the fault location and avoid tripping when the fault character changes.  By using fault detectors to determine the existence of a fault, the logic at each terminal for combining the sig-nals is simplified and security against false tripping is improved.

Abstract: WINDROW REVERSER FOR WINDROWER DRAPER HEADER                 ABSTRACT OF THE DISCLOSURE        A laterally shiftable draper header for a windrower is disclosed wherein a pair of draper sections are laterally shiftable on the header subframe to vary the position of the crop discharge opening between left, right and central positions.  When the discharge opening is positioned at a central location between separated draper sections, it is necessary that the draper conveyors rotate in opposing directions to deliver crop material to the discharge opening.  However, when the draper sections are positioned adjacent one another and shifted to one side of the machine or the other it is necessary for the draper conveyors to rotate in the same direction to convey crop to the discharge opening.  A reversing mechanism for changing the direction of rotation of one of the draper sections relative to the other in response to the relative position of the other draper section is provided and includes a push rod for sensing the proximate location of the other draper section to cause the associated draper conveyor to reverse direction of rotation.
